Study on effective factors on attraction and capture of Grape berry moth, Lobesia botrana Denis and Schiffermüller (Lep.: Tortricidae) in pheromone traps

Grape berry moth (GBM), Lobesia botrana (Denis et Schiffermuller) is the main pest of most vineyards in Iran and the world. Sex pheromone, it has played an important role in the control and detection of this pest. Many factors effects on yield pheromone trap. In this study, were investigated the effect of trap type and color, height, direction and base of placed trap, dose response dispenser in the field on trap efficiency. For this purpose, experiments were conducted in a randomized complete block design with four replications in the Mazdeh region of Khalilabad city in 2014 year. The results showed that, there was no significant difference in male capture between treatments, in trap height, direction, color, and dose response. The maximum capture was observed in 1.5 meter height (1.78±0.66), delta type (1.95±0.45), transparency trap (1.70±0.14), west direction (4.37±1.26) and 2 dispensers in trap (0.94±0.41). Also, the maximum capture was observed in traps placed on base vine (1.58±0.19). Based on this study, it is suggested for monitoring trap GBM, usage of delta trap with 1-2 dispensers in trap placed on west direction and 1.5 meter height on vine tree.
